An airgun…what gun to buy and why - CharlieDaTuna

About caliber…briefly. There are four basic caliber of guns mass manufactured today. They are the .177, the .20, the .22 and the .25. A rule of thumb is to use a larger caliber, say a .22 if the gun is to be used predominantly for hunting. .20 caliber kinda gives you the best of both worlds. ................
